This Crockpot Pierogi Casserole with Kielbasa is the ultimate comfort food — tender pierogi layered with smoky kielbasa, creamy sauce, and melty cheese, all slow-cooked to perfection.

Ingredients

  • Frozen Potato and Cheese Pierogi: 2 (16 oz) packages – the hearty, cheesy base of the casserole.
  • Kielbasa: 1 pound, sliced – adds smoky, savory depth.
  • Cream Cheese: 8 oz – makes the sauce rich and tangy.
  • Sour Cream: 1 cup – adds creaminess and a slight tang.
  • Shredded Cheddar Cheese: 2 cups – melts into gooey perfection.
  • Milk: ½ cup – helps thin the sauce for smooth layering.
  • Garlic Powder: 1 tsp – brings savory flavor.
  • Onion Powder: 1 tsp – adds depth without chopping.
  • Salt: ½ tsp – to balance and enhance flavors.
  • Black Pepper: ½ tsp – adds a little kick.
  • Butter: 2 tbsp – for richness and added flavor.
  • Chopped Parsley (optional): For garnish – adds freshness and color.

Instructions

  1. Preheat Your Equipment: Prep your crockpot with nonstick spray.
  2. Combine Ingredients: In a bowl, whisk together cream cheese (softened), sour cream, milk, garlic powder, onion powder, salt, and pepper until smooth.
  3. Prepare Your Cooking Vessel: Optionally, brown kielbasa slices in a skillet for 3–4 minutes per side.
  4. Assemble the Dish: Layer half the frozen pierogi on the bottom of the crockpot. Add half the kielbasa, then spoon over half the sauce and sprinkle with 1 cup cheese. Repeat layers.
  5. Cook to Perfection: Cover and cook on low for 4–5 hours or on high for 2–3 hours until hot and bubbly.
  6. Finishing Touches: Sprinkle remaining cheddar cheese on top, cover, and let melt for 10 minutes. Garnish with parsley if using.
  7. Serve and Enjoy: Scoop into bowls and serve warm.

Notes

  • Spray crockpot with nonstick spray to avoid sticking.
  • Browning kielbasa adds extra flavor but is optional.
  • Slightly thaw pierogi before layering for even cooking.
  • Add sautéed mushrooms or onions for extra flavor.
